Abstract

A sterile hydrogel composition comprising a crosslinked polymer, wherein the crosslinked polymer is an oxidation product of a thiol-modified hyaluronan and wherein the thiol-modified hyaluronan has a degree of modification of hyaluronan with thiol moieties of more than about 80 μmol per gram polymer, wherein the thiol-modified hyaluronan has a degree of modification of hyaluronan with thiol moieties of less than about 280 μmol per gram polymer, wherein the composition has a residual thiol content of less than 20% in respect to the degree of modification of the thiol-modified hyaluronan.
